Self-Powered IDE to CF Adapters

The MicroDrive Turbo comes with a self-powered IDE to CF Adapter with a pre-setup
CF Card. Self-powered refers to the IDE to CF Adapter which uses power supplied on
Pin 20 of the IDE connector and does not require an external power source. This
means the Apple II Computer can supply power to the CF Card and no other power
source is needed.
Boards sold from 2006 to Mid-2008 will have +5v connected to Pin 20 of the IDE
Connector in the form of a small jumper wire on the rear of the board. Later boards
have a small trace added to the face, left side of the board.
Over the years some users insisted on trying to install the CF Adapter backwards
which would cause a short and burn the added trace from the board. So all boards
from late 2017 and on have a fuse added to the small trace for added protection.
The photo below on the right with the fuse displays what the added trace looks like
and its location.
